144 TWENTY-FOURTH REPORT ON THE STATE MUSEUM. 



rule among the Lepidoptera, when the pupa first divests itself of its 

 larval covering, its antennae-, leg-, and wing-cases are readily separable 

 from the body-case on which they lie, but in a brief time are firmly 

 cemented to it by the drying and hardening of the viscid coating 

 which overspreads it. This species, however, is an exception to the 

 rule, and the first which has been observed by me. * Upon opening 

 its cocoons, the above mentioned organs are found disconnected (except 

 basally) from the pupal body. In its extruded pupa-case may usually 

 be seen the antennas-cases extended in the form of the antique lyre 

 quite in advance of the other members, the leg-cases brought up from 

 beneath the wing-cases, the latter quite separated at their apices from 

 the abdominal region, and giving indication of having rendered 

 efficient service in the escape from the cocoon. 



Pupa. Its color is essentially that of the contained imago show- 

 ing through the translucent shell, being ochreous on the thorax and 

 attached members, and lutescent on the abdomen. It is of an oval 

 shape, slightly contracted at the base of the abdomen, its extremities 

 rounded, the terminal segment blunt and without processes. The 

 head-case projects moderately beyond the prothorax ; the eye-cases 

 are prominent with a shining mamilla intermediately. The antennae- 

 cases showing distinctly at their mesial carination the curved tips of 

 the pectinations, extend in the male to the tips of the wing-cases, and 

 in the female to those of the anterior leg-cases. The posterior leg- 

 cases protrude from beneath the wing-cases, nearly across the eighth 

 segment. The wing-cases are rounded at their inner angle, and 

 extend half-way over the seventh segment ; under a lens, they show 

 distinctly the crinkled black hairs of the disc of the wing. The 

 thoracic divisions are distinct, not being cemented together; the 

 pronotum is thrice as broad as long, excavated in front, convex 

 behind, depressed medially, its posterior angles subquadrate, with a 

 protuberance near its anterior margin on each side ; the mesanotum 

 is one-half longer than broad, its sides subparallel, and its hinder 

 margin rounding over the metanotum to nearly its posterior margin; 

 the metanotum is a little longer than the pronotum, and corrugated 

 longitudinally on each side. The abdominal segments, under a lens, 

 have fine longitudinal wrinkles anteriorly ; the incisures are rather 

 deep. The eight abdominal stigmata are visible ; the seven anterior 

 ones are broadly oval, with prominent margins, and have a small 

 tubercle behind each ; the last one is linear, without a raised margin 



*In some of the Tineidae the limbs are partially free. Packard, in The American Naturalist, 1871,
